Burthorpe was once the RS gold capital of Asgarnia before the time that the King fell ill. As Burthorpe was once the capital, you'd expect a huge, magnificent city with huge walls, tall towers and the most elite security... Well.. I have a surprising discovery to reveal to you. It isn't very grand. There aren't any walls apart from the castle. That would make it susceptible to attack by trolls. Also the castle wall that is on the side where they would attack is damaged. However, scaffolding is in place however it's not being repaired or protected by guards. That's mad! It's also extremely boring and dull. It is also unusable because the city has never been painted.
Imagine a city that was larger than Falador, with huge walls and gates that protect the entrances, and small spaces for cheap RuneScape gold guards to relax or make tea and eat during their shift. Every area of the castle would have an impressive, tall tower, filled with important rooms.
